Nvidia patents method to tweak data links based on noise levels
Nvidia describes a system that monitors the quality of a data connection by calculating a specific noise metric. It then automatically adjusts the error-correction settings or receiver parameters to reduce data errors.
In the filing’s own words
Technologies for optimizing post-FEC bit error rate (BER) performance of a Forward Error Correction (FEC) system are described. A controller is coupled to an FEC circuit and a receiver circuit. The controller receives equalized error data from the receiver circuit and determines, using the equalized error data and a nominal signal power, a signal-to-noise ratio (SNR) deviation metric, the SNR deviation metric being indicative of an estimated post-FEC BER of the FEC circuit. The controller adjusts, based on the SNR deviation metric, at least one of a FEC parameter of the FEC circuit or a link parameter of the receiver circuit to decrease the estimated post-FEC BER. This improves the post-FEC performance of the FEC circuit.
What exactly they claim (claim 1)
1. A communication system comprising: a receiver circuit; a Forward Error Correction (FEC) circuit operatively coupled to the receiver circuit; and a controller operatively coupled to the receiver circuit and the FEC circuit, wherein the controller is to: receive equalized error data from the receiver circuit; determine, using the equalized error data and a nominal signal power, a signal-to-noise ratio (SNR) deviation metric, the SNR deviation metric being indicative of an estimated post-FEC bit error rate (BER) of the FEC circuit; and adjust, based on the SNR deviation metric, at least one of a FEC parameter of the FEC circuit or a link parameter of the receiver circuit.
